Daniel, I've been trying it myself using the syntax like:

 gcc -Wall -o libvirt-test `pkg-config --libs --cflags libvirt`
-lpthread libvirt-test.c

to run it both as root and non-root and also with a guest running and
not-running and it never failed for me on my Intel(R) Core(TM)2 Duo CPU
T9600  @ 2.80GHz i686 system with 4 GB of RAM (just 2.9 GB really
available because of 32-bit system).

I was thinking of adding this into the tests directory and putting it
directly to the tests run by `make check`. What do you think about this?
